WORDPRESS BACKEND SCRIPT CHANGING mysql_() TO mysqli_()

WORDPRESS BACKEND SCRIPT CHANGING mysql_() TO mysqli_()

Please note, we are looking for someone for ongoing work,

This is the first job spec we are looking for and for someone who understands wordpress backend scripts, this should be a simple job that would not take much of your time

The below information is what we have been provided that needed amending, If you are able to fix this for us within 24 hour and understand Wordpress backend, we have a pretty simple backend, we are happy to use you for a few other job requirements as well!

The issue has to do with the extension that was deprecated in PHP 5 version and removed in PHP version 7. I would advise to please check the script and start using mysqli_() instead of mysql_(). Even mysqli_() is enabled in newer versions of PHP, please ensure that the said function should be used based on the error.

Every time we try and 'view' or 'edit' any of our pages in our backend we get the following message, so the above should fix this, the main aim is to fix this issue:
Error thrown Call to undefined function mysql_query()
